Applications
Application field:
Cerium boride is mainly used as a coating for hot cathodes, or the hot cathode is directly composed of cerium hexaboride crystals. Cerium hexaboride (CeB6) and lanthanum hexaboride (LaB6) are often used as some high-current hot cathode coatings. Hexaboride has a low work function, about 2.5 eV, and has a certain tolerance to cathode contamination. Cerium boride cathodes have lower evaporation rates than lanthanum boride at 1700 K, but they become uniform at 1850 K and even higher evaporation rates above that temperature. Cerium boride cathodes have a 50% longer life than lanthanum boride due to their higher carbon pollution resistance. The brightness of the boride cathode is ten times that of the tungsten cathode and its life is 10-15 times that of the tungsten cathode. Some laboratory tests have shown that CeB6 is more tolerant to the negative effects of carbon pollution than LaB6. They are commonly used in, for example, electron microscopy, microwave tubes, electron beam etching, electron beam welding, X-ray tubes, and free electron lasers.It is a refractory ceramic material
